Abstract: A safety helmet fan system includes a fan housing carrying a first fan on a first side of the fan housing and a second fan on a second side of the fan housing and configured to be mounted, by a mount connector located between the first side and the second side, on an exterior of a safety helmet shell above a brim of the safety helmet shell, and an elongate cooling air duct connected to the fan housing to direct cooling air flow from the fan housing around the brim and into an interior of the safety helmet shell.

Abstract: A multiple component system is provided for mounting on a safety helmet and includes a first component housing carrying a first component, and a second component housing carrying a second component. Each housing has a first mount connector and a second mount connector located on opposing faces of the housing. The first mount connectors are configured to be compatible with the second mount connectors to provide quick release mount connections between the housings.

The duct can have a flexible construction that allows the duct to be selectively reshaped to accommodate different safety helmet brim configurations. The duct can have a releasable connector configured to releasably connect the duct to a brim of a safety helmet shell.

Abstract: An offset tape measuring tool marked with standard English measurements includes integrated indicia for quick determination of distance between bends for a given offset depth and offset angle when installing conduit. Additional indicia may be included for the measurement of the shrinkage of the conduit with respect to the specified offset depths and angles. The integrated invention may be part of a standard tape measure strip to provide a convenient multi-purpose tool. Although the tool eliminates any external calculations or table reference typically necessary when bending conduit to clear an obstacle, it still provides an optional reference card for unique bends.
